LOOM.

App1ication filed January 26, 1923.

1 0 nZZ whom it may concern:

Be it known that I, CLARE H. DRAPER, a citizen of the United States, residing at I-Iopedale, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. p

The present invention relates to an improvement in looms.

In the loom illustrated in the application.

filed by me Sept. 18, 1922, Serial No. 588,- 7 76, an anti-bang device was employed which operated, when the protector mechanism was thrown into operation, to draw the whip roll forward so as thereby to release the tension on the warp in case the shuttle was not properly boxed. It sometimes happens that under such circumstances the shuttle would be in front of the temple and then as the lay moved forward, the shuttle would push the temple back. This it does without injury to the loom but the pressure of the shuttle upon the yarn be tween it and the temple is sometimes sufficient to break or cut the warps at this point. The object of the present invention is to provide a construction of anti-bang apparatus in which, when the protector mechanism is operated, the loom temples will be pushed backward out of the way of the shuttle in case the shuttle should happen to be opposite the temple. To this end, the invention consists in the loom hereinafter described and particularly defined in the claims.

In the accompanying drawings illustrating the preferred form of the invention, Figure 1 is a sectional elevation of parts of the loom sufficient toillustrate the invention; and Figure 2 is a similar sectional View with parts omitted showing the operation of the contrivance for pushing back the loom temples when the protector mechanism is operated.

The illustrated embodiment of the invention is described as follows: The warp comes from the warp beam over the whip roll 38, thence through the warp drop wires and heddles to the shed and thence to the breast beam, passing over the sand roll 10 and Serial No. 615,010.

thence to the wind-up roll, not shown.. The lay 11 carries dagger rods 18 supported in sultable bearings on the swords 12 and con nected and actuated in the usual manner. from the blnders of the shuttle boxes. When there is no shuttle present in the shuttle box, the binder is advanced and turns the dagger rod 18 in the direction to drop the dagger 20 behind the frog secured to the frog slide 32. The frog slides are connected by means of the links 34 with the whip roll 38 and in the event that the shuttle is. not boxed, the daggers are dropped; the frog slides move forward; and the loom is brought to rest, the frog slides being con nected with a knock-01f for the shipper lever in the usual manner.

In order to prevent the shuttle from striklng the temple in case it should find itself opposite the temple when the protector mechanism was operated, a contrivance is employed to push the temple forward out of the way of the shuttle. The temple 21 is provided with a heel 22 which engages the lay and pushes the temple forward with the advancing lay, It is apparent from inspection of Fig. 1 that, in case the shuttle was present between the reed 23 and the temple, the warps would be pressed by the shuttle against the temple and injury to the warps would sometimes occur. In accordance with the present invention, a bunter 40 is pivoted at 42 on the underside of the lay beam. In normal position the bunter is below the heel 22 of the temple. When the dagger rod is turned, owing to the absence of the shuttle in either shuttle box, an arm 43 mounted on the dagger rod and engaging an arm 44 on the bunter 40 turns the bunter so as to raise. the front end thereof in the path of the heel of the temple. The arms 43 and 44 have toothed connections shown as oneand twotoothed' segmental gears. The lay is provided with two bunters, one opposite the heel of each temple so that when the daggers are dropped, the hunters are raised and they strike the heels of the temples and push the temples back and so prevent the shuttle from striking a blow on the temple during the advancing movement of the lay.

While the anti-bang device is adapted for use in looms generally, it is more particularly important in connection with high speed looms such as the loom of the application hereinbefore referred to. In that loom the high speed of operation was such that'to bring the lay to rest in the short dis- 'tance permitted by the usual protector mechanism would severely strain the parts and break some from time to time and so it was that the anti-bang device was employed therein. The bringing of the loom to rest when provided with this anti-bang device is more gradual and saves the loom the severe stress and strain incident to the stopping of the loom upon the initiation thereof tion, a lay, temples, protector mechanism lhavlng anti-bang I mechanism, and means operated by the protector mechanism and adapted to be interposed between the lay and the temples for pushing the loo-m temples forward upon operation of the protector mechanism.

2. A high speed loom having, in combination, a lay, protector mechanism, temples provided with heels for engagement with r.

the lay to push the temples forward upon each forward beat of the lay, hunters mounted on the lay, connections between the hunters and the protector mechanism operating on actuation of the protector mechanism to swing the bunters into position to engage the heels of the temples and thereby push them forward out of range of possible blow by the shuttle on the lay.

3. A high speed loom having, in combination, a lay, a whip roll, a breast beam, a protector mechanism including an anti-bang device, temples having provision for normal actuation by the lay, and means mounted on the lay and controlled by the protector mechanism for engaging and pushing for- Ward the temples upon actuation of the protector mechanism.
